ROYAL JV. CATHCART AND JOHN P. CARPENTER, OF EL'KHART, INDIANA.

MUSIC-RACK.

To all whom it may concern Be it known that we, ROYAL 1V. CATH-v oan'r and JoI-IN P. CARPENTER, citizens of the United States, residing at Elkhart, county of Elkhart, and State of Indiana, have invented a new and useful MusicRack, of which the following is a specification.

Our invention relates to improvements in music racks and particularly to a type of music rack which has a revoluble frame for holding the sheet of music, and which permits of reading the music 011a sheet secured therein on both obverse and reverse sides thereof without the removal, or turning, of the sheet of music.

The objects of our invention are, first, to provide a revoluble music rack, 01' frame, whereby both the obverse and reverse sides of a sheet of music may be read without removing the sheet of music from the frame; second, to afford facilities for the adjustment of the upper frame arms to accommodate various sizes of sheet music. We attain these objects by the mechanism illustrated in the accompanying drawings, in whieh Fi ure 1 is a front elevation of the entire music rack. Fig. 2 is a side elevation thereof with the revoluble base member shown in fragmentary section. Fig. 3 is a plan view of the lower end of the base member, revoluble on a non-revoluble standard. Fig. 4. is a rear elevation of the music rack with the lower locking arms open and the upper locking arms closed. Fig. is a fragmentary plan view of the outer end of a lower arm member, showing the lug for receiving the lower locking arm.

Similar figures refer to similar throughout the several views.

The invention consists essentially of a non-rotative frame support 1, and a rotative sheet music holding frame pivotally mounted thereon. The rotative frame embodies generally, a frame shaft consisting of base member 1 and shaft 5 rigidly fastened together for pivotal operation, the sleeve member 6 carrying upper arm supports and upper frame arms 19 and 20 mounted thereon, lower frame arms 25 and 26 mounted upon the frame shaft base, upper looking arms 23 and 24:, an upright swinging clamp hinged at the shaft base, and lower locking arms 30 and 31 pivotally mounted on the clamp memberlO.

On the drawings, 1 is the bearing standard which is non-revoluble and carries the entire parts Specification of Letters Patent.

music rack frame. Its lower end may be attached to any suitable base plate or tripod. Its upper end is the pivot shaft upon which the music rack revolves, and which projects into the socket 14 of the base member i. working freely therein to insure ease of revolution. On one side of member 1 is fastened a spring pawl 2, being secured in position by the screw 3. It projects upward and is adapted to engage either one of the two oppositely disposed slots formed in the outer periphery of the annular base member 4 when the same is in alinement with the slot 16 which is formed on one side of the annular enlargement of member 1.. When arranged within slot 16 any lateral movement of the pawl 2 is arrested. Shaft 5 is firmly fixed in base member a by pin 38. At its top is locking spring 8 held in position by screw 9. lhe T shaped member 4 has supporting arms 25 and 26 fastened to it by pins 36 and 37 which permit of free action upward on the part of arms 25 and 26. Normally, arms 25 and 26 rest upon the brackets 17 and 17 which are lateral projections from member 1. Lugs 28 and 29 are formed at the outer end of arms 25 and 26, which are preferably of angle iron.

Attached to the base member 4 and in hinged relation therewith is the clamping member 10 the upper end of which is adapted to be locked against the shaft 5 by the locking spring 8. This member 10 has a hinge 11 fastened to its lower end, which in turn is fastened to the lower end of member 41, in hinged relation, by the pin 12, permitting of free and easy backward and forward movement of the entire member 10 when disengaged with spring 8. "When member 10 is locked against the shaft 5 by the spring 8 it is in the position indicated by the dotted lines 39. Fastened to clamp member 10 is the locking arm 30 held by the pin And attached to locking arm 30 is locking arm 31 held to arm 30 by the pin 32. Arms 30 and 31 are preferably of flat metal, freely movable at the pins 32 and 33, collapsible against member 5, and adapted to be secured, at their outer ends, by the lugs 28 and 29 at the outer end of members 25 and 26.

Shaft member 5 is preferably of rectangular section to prevent a circular motion of the sleeve arm bearing member 6 which is adj ustably. mounted on said shaft 5 and which may be set and fixed in any desired position thereon by the use of the set screw 7 Fastened to sleeve member 6 are arms 19 and 20, preferably of flat metal, and held to (S by pins 21 and 22 upon which they are freely movable upward and downward to a horizontal plane. The pins 18 and 18 set in member 6 prevent arms 19 and 20 from falling below a point at right angles to member 5. Attached to arms 19 and 20 by pins 34 and 35 and freely movable on same are retaining arms 23 and 2st, preferably of flat metal, somewhat bowed, and in concave relation to arms 19 and 20 when parallel therewith. Frame arms 19, 20, 25 and 26 freely fold upwardly on the pins 22, 21, 36 and 37, respectively, to reduce the bulk of the complete frame and to enable its ready transportation.

To place and clasp a sheet of music in the rack, or frame, the various members and parts are operated as follows: Clamp member 10 is disengaged from the locking spring 8 and drawn away from the shaft 5; arms 30 and 31 are lifted upward out of engagement with lugs 28 and 29 and placed in about the position shown in Fig. 1; retaining arms 23 and 2a are forced upward at right angles to arms 19 and 20. The frame is then wide open, and the sheet of music is inserted between members 10 and 5 and brought forward and downward until the lower end thereof rests upon the flat surface 27 of the arms 25 and 26. Member 10 is then pressed forward against the sheet of music, which is clamped between shaft 5 and member 10 thereby, and the upper end of 10 forced into engagement with looking spring 8 which holds it firmly against the sheet of music. Retaining arms 28 and 2% are then drawn downward and outside of the sheet of music until practically parallel with arms 19 and 20, thereby firmly holding the upper outside corners of the sheet of music. Finally, the arms 30 and 31, which are carried by member 10 and movable therewith, are drawn downward and the outer ends thereof pressed into the hook formed by the lugs 28 and 29, thereby firmly holding the outside lower corners of the sheet of music. To rotate the entire frame the spring pawl 2 is retracted from slot 15. The frame is then freely revoluble upon the pivot end of member 1 arranged within the socket 14, and may be rotated either way. If pawl 2 is held retracted the frame may be rotated any number of times. But if not so held retracted, the pawl 2 will spring; forward into the slot 15 which first alines with slot 16 and thereby locks the frame against further rotation until again retracted.

Vhat we claim is 1. A sheet music rack comprising a nonrotative frame support, a frame shaft mounted upon said frame support and in pivotal relation therewith, a sleeve member adjustably mounted upon said frame shaft having frame arms thereon and clamps on said arms, frame arms mounted at the base of said frame shaft and revoluble therewith,
